[ausev] Battery choices

[Rob H]

As a rule, it seems that for equal capacity, pb is 10x the weight for 1/10
the cost of Li.  Li options do not supply as much current so the max power
out (P=IE) is limited.

For Pb conversions, you should estimate 1/3 of the GVW as lead.  Too much
will cut your range, too little will (of course) cut your range.

50 miles at highway speed will take some effort.
